Why does urine have a large pH range?
A high urine pH may be due to: Kidneys that do not properly remove acids (kidney tubular acidosis, also known as renal tubular acidosis) Kidney failure. Stomach pumping (gastric suction)
What factors contribute to pH changes in urine?
A diet rich in citrus fruits, legumes, and vegetables raises the pH and produces urine that is more alkaline. Most of the bacteria responsible for urinary tract infections make the urine more alkaline because the bacteria split urea into ammonia and other alkaline waste products.
What is the range of urine pH?
The American Association for Clinical Chemistry says the normal urine pH range is between 4.5 and 8. Any pH higher than 8 is basic or alkaline, and any under 6 is acidic.
What does large leukocytes in urine mean?
Higher levels of leukocytes in the bloodstream may indicate an infection. This is because WBCs are part of the immune system, and they help fight off disease and infection. Leukocytes may also be found in a urinalysis, or a urine test. High levels of WBCs in your urine also suggest that you have an infection.
What does urine pH indicate?
A urine pH test measures the level of acid in urine. Some types of kidney stones are more prone to develop in alkaline urine and others are more likely to from in acidic urine. Monitoring the urine pH may be helpful in preventing the formation of kidney stones.
What does high pH mean?
pH is a measure of how acidic/basic water is. The range goes from 0 – 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pHs less than 7 are acidic while pHs greater than 7 are alkaline (basic).
What does a low pH in urine mean?
If your urine sample has a lower-than-normal pH, this could indicate an environment conducive to kidney stones. Other conditions that prefer an acidic environment are: acidosis. diabetic ketoacidosis, which occurs when ketones build up in the body. diarrhea.
What does a 7.0 pH in urine mean?
The normal range for urine pH is 4.5 to 7.8. Very alkaline urine (pH > 7.0) is suggestive of infection with a urea-splitting organism, such as Proteus mirabilis. Prolonged storage can lead to overgrowth of urea-splitting bacteria and a high urine pH.
What causes positive nitrite in urine?
The presence of nitrites in urine most commonly means there’s a bacterial infection in your urinary tract. This is usually called a urinary tract infection (UTI). A UTI can happen anywhere in your urinary tract, including your bladder, ureters, kidneys, and urethra.
How do I read my urine test results?
Normal values are as follows:
- Color – Yellow (light/pale to dark/deep amber)
- Clarity/turbidity – Clear or cloudy.
- pH – 4.5-8.
- Specific gravity – 1.005-1.025.
- Glucose – ≤130 mg/d.
- Ketones – None.
- Nitrites – Negative.
- Leukocyte esterase – Negative.
What happens when pH is too high?
The pH is a measure of the water’s balance between acidity and alkalinity. If the pH isn’t properly balanced, problems can occur. Water pH ranges from 1 to 14. Water with a pH that’s too high also can cause skin rashes, cloudy water and scaling on pool equipment.
Should urine be acidic or alkaline to prevent UTI?
When the urine has less acid (more alkaline), there is a greater likelihood of bacteria growing at a rapid rate and as a result a bladder infection can occur more easily. So, it is beneficial to keep your urine naturally acidic….

What is the normal range of pH in urine?
According to the American Association for Clinical Chemistry, the average value for urine pH is 6.0, but it can range from 4.5 to 8.0. Urine under 5.0 is acidic, and urine higher than 8.0 is
Why would my doctor order a urine pH level test?
Your physician may order the urine pH level test to determine whether your medications are making your urine too acidic. The urine pH level test can also determine the best medication to prescribe when you have a urinary tract infection.
Is urine pH 7 acidic or alkaline or acidic?
A urine pH of 4 is strongly acidic, 7 is neutral (neither acidic nor alkaline), and 9 is strongly alkaline. Sometimes the pH of urine is affected by certain treatments.
What affects the pH of urine after collection?
Special considerations: Urine pH can be affected by various factors after collection such as leaving the urine standing in an uncovered container. Bacteria usually increase the pH as they break down urea in the urine to ammonia. A diet high in citrus fruits, vegetables, or dairy products can increase your urine pH.
